Risa places 6 bags an equal distance from one another. The distance between the first bag and the sixth bag is 110 cm. If Risa adds another 13 bags that are equal distance apart,
- How many gaps will there be between the thirteenth bag and the nineteenth bag?
- What is the distance between the 13th bag and the 19th bag?
(a)
Number of gaps between 6 bags
= 6 - 1
= 5
Distance between two bags
= 110 ÷ 5
= 22 cm
Number of gaps between the thirteenth and the nineteenth bag
= 19 - 13
= 6
(b)
Distance between the thirteenth and the nineteenth bag
= 6 x 22
= 132 cm
Answer(s): (a) 6; (b) 132 cm
